- Vhat are the two types of muscle movement categories? Give an example for both. Describe Swammerdam's experiment and Galvani's experiment with frog legs. What did they tell us about muscle contraction? What is the sliding-filament model for muscle contraction? Describe the role of actin and myosin of sarcomeres in the model (be specific). Describe how an action potential triggers muscle contraction. Know the specific molecules involved. . Describe the structural and functional differences between smooth, cardiac and skeletal muscles. What are the three types of skeletal muscle fibers and how do they differ in structure and function? Next « Previous MacBook ProHow does the body provide energy for endurance exercisesMove Making Connections, Student Laboratory Packet, page 5 A2. How Does Fatigue Affect Muscle Performance? A condition known as muscle fatigue occurs when certain waste products of muscle cell activity build up in the cells. Until these waste chemicals are removed, the fatigue will continue. Do the Following Activity Hold a spring-type clothespin between your thumb and index finger. Pinch the ends together completely (until the two ends touch) and release them. Do this as rapidly as possible for one minute. Record the number of times you could squeeze the clothespin in one minute: Try the activity again, doing it the same way and using the same two fingers as before. Record the number of times you could squeeze the clothespin the second time: Answer the Following Questions Some people are able to squeeze the clothespin more times in a minute than others. Suggest a possible explanation for this. Could you do as many in a minute the second time as you could do the first time? Provide a…
- What are the benefits when performing movement based exercises and how does your body react?aerobics exercise - give me short term goal - give me long term goalHow is the list below to be properly put in order to describe a muscular contraction? 1. Calcium causes exocytotic release of Acetylcholine into the synaptic gap; all this happens at an area called the neuromuscular junction2. ATP is consumed which allows myosin to "pivot" the myosin head, which pulls actin toward it.3. This process is repeated multiple times and is called the "sliding filament theory".4. Myosin filaments perform "crossbridging".5. Calcium is released and circulated throughout the muscle cell6. The brain predicts the action necessary and decides which muscles and how many "motor units" are needed to perform that action.7. Tropomyosin moves to reveal the active site of the F-Actin strand8. Upon reception of a calcium ion, the Troponin complex becomes activated9. Proteins embedded in the Sarcolemma receive enough of the ACH neurotransmitter to generate an electrical impulse.10. The electrical impulse is perpetuated throughout the muscle fiber.11. A nervouse impulse is…

- Calcium initiates smooth muscle contraction by leading to the phosphorylation of calcium channels leading to the phosphorylation of myosin • activating myosin light chain phosphatase removing tropomyosin from actinWhy is ATP required for skeletal muscle contraction? Choose all that apply. Release myosin and actin and reset the myosin head ATP causes rigor mortis Attaching ATP to the myosin head initiates the power stroke Pump calcium ions back into the sarcoplasmic reticulum via active transport ATP is not required for skeletal muscle contractionWhat stimulates Golgi tendon organs? A muscle is contracting with minimal tension. A muscle is stretched nearly to its limit. A muscle has become metabolically active. A muscle starts to relax after strenuous exercise.
